Answer:
0.0000016
Step-by-step explanation:
(8×10^-3)×(2×10^-4)
=8×10^-3 × 2×10^-4
= (8×2) × (10^-3 × 10^-4)
=16 × 10^(-3) + (-4)
= 16 × 10^ (-3-4)
=16× 10^(-7)
= 0.0000016
Answer:
90 sq in.
Step-by-step explanation:
The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50
Elimination method was used.
Step-by-step explanation:
Let,
Cost of one large pizza = x
Cost of one breadstick = y
According to given statement;
4x+y=34.46 Eqn 1
2x+y=18.48 Eqn 2
Subtracting Eqn 2 from Eqn 1
Dividing both sides by 2
Putting x=7.99 in Eqn 2
The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50
Elimination method was used.
